In this paper we report Strontium Cerium Oxide (Sr2CeO4) blue phosphor was synthesized via solid state reaction method using strontium carbonate SrCO3 and cerium oxide CeO2 as raw materials. The samples were characterized by Thermo analytical techniques (TG, DTA, DTG and DSC) in nitrogen atmosphere, Fourier transformation infrared (FTIR) spectroscopy, and Photoluminescence at room temperature. Thermal analysis indicates that Sr2CeO4 phosphor can be prepared at temperature higher than 1100 °C. In excitation spectra two excitation peaks were located at 262 and 399 nm respectively. The emission spectrum was a broad band peaking at 470 nm, which was suitable for the doping of rare earth ions. The color co-ordinates for the pure Sr2CeO4 were x = 0.1918 and y = 0.2483. This material has potential for applications in the field of emission devices.
